SHOE-KNIFE.

SPECIFICATION forming part of Letters Patent No. 452,999, dated May 26,1891.

Application filed October 16, 1890. $erial No. 368,251. (No model.)

To all whom it may concern.-

Be it known that I, GUYoN T. FISHER, a citizen of the United States,residing at Lansing, in the county of Ingham and State of Michigan, haveinvented certain new and useful Improvements in Shoe-Knives; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings,

and to the letters of reference marked there.

on,which form a part of this specification.

This invention relates to new and useful improvements in shoe-knives;and it consists in a certain formation and arrangement of parts,producing a knife the handle of which afiords a firm grasp for the hand,anduthe blade of which may be readily adjusted longitudinally to form along or short blade or to extend the blade as it wears away, as desired,all of which will be hereinafter more fully set forth, and the essentialfeatures of the device pointed out particularly in the claims.

In the accompanying drawings, forming a part of the specification,Figure 1 is a side elevation of my improved knife. Fig. 2 is a verticallongitudinal section through Fig. 1. Fig. 3 is a perspective view of theseveral parts of the knife detached.

Referring to the letters of reference, A indicates the handle oftheknife; B, a spring loop or yoke that environs said handle andreceives the edges of the k nife-blade between its free ends.

0 indicates the ferrule that receives the free ends of the loop B, andthrough which the blade extends.

D indicates the blade of the knife, and E a recess or socket in thehandle that receives said blade.

The handle A is made preferably of wood, and is essentially ellipsoidalin form, as this form renders the handle strong and substantial, andaffords a firm full grasp that does not tire the hand. The groove 2; inthe perimeter of the handle, and which extends longitudi nally aroundthe same, receives the spring loop B therein, so that no portion of saidloop extends beyond the surface of the handle, as

shown in Fig. 2. The free ends 6 of said loop stand parallel for a shortdistance, and are provided in their adjacent faces with the grooves c 0,adapted to receive therein the edges of the blade D. The ferrule 0receives the free ends e of the loop B, and confines them therein, sothat the grooves c in the ends of said loop will register with theslot 1) in the outer end of said ferrule. (Shown in Fig. 3.) Theknife-blade D is passed through the slot 1) in the end of the ferruleand between the ends c of the spring-loop B, the edges of the bladelying in the grooves c in the ends of said loop, and the rear end ofsaid blade projecting into the recess or socket E within the handle. Theferrule C is provided with a setscrew a passing therethrough, the innerend of which bears upon one end e of the springloop, whereby by means ofsaid screw the ends 6 of the spring-loop may be firmly clamped upon theblade, thus securely holding said blade in place, as clearly shown inFig. 2. When it is desired to adjust the blade D, the set-screw a isloosened, when the ends e of the loop B will spring apart, releasing theblade, permitting a longitudinal adjustment thereof, whereby the blademay be extended or reduced in length, in accordance with the work to beperformed or the use to which the knife is to be adapted, and when setthe blade may be again secured by means of the set-screw a, as beforedescribed.

It will now be apparent that the herein-described shoe-knife is cheapand simple of construction, the blade of which may be readily adjustedand securely held when set, and that the ellipsoidal form of the handleenables the knife to be firmly held and used for a great length oftimewithout tiring the hand. This is a veryimportant feature, as the knifeis to be used for cutting sole-leather, to which use it is especiallyadapted by means of the firm hold which its handle affords.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In combination with the handle ellipsoi dal in form and having asocket along its longitudinal portion, the spring-metal yoke encirclingsaid handle, said yoke having the grooves c, the ferrule, the set-screwand slot ICO in said ferrule, and the-knifc-blade adjustahly I bladeadapted to pass through the slot of the attached, as set forth. ferruleand to be clamped by the yoke. 10
